In most case , element in cell will be re-use for memory especially in very
long list, but if add event for this element, here will generate a new view for
this element,if it's nil due to a getter method whether it is off-screen.

For instance, image element in cell will re-use if it is disappear in vision area,
loaded again while it back to visual area. In this case , when it disappear, just
add event such as click, touch and so on , it will then create a new view,
and load image again, although it is off-screen.

If the view is not loaded, so won't add gesture or call this view getter to create
any view until the view is loaded, then it will init events according to record in

[WEEX-96][iOS] bug-fix about timer exposed on JSContext
  Timer exposed on the JSContext, so user can access the function,
though JavaScript, it has setTimeout and setInterval functions, those
function switch to global queue while execute javaScript code, it may
have potential crash about thread safe problem, and for setInterval
function, the timeId can not auto-increment, so it is hard to clear it at
the end of program.
  Overview the code, the difference between timer module and the
JSConext timer is  the execution path is more shorter, the JSContext
timer can execute javascript function immediately, but the timer module
instruction must be dispatched by weex sdk just like the common modules,
the JSContext can be used in canvas scene.
